Description
Technical field
The present invention relates to a kind ofly be used for the equipment of its electrochemical treatment, especially electroplate or etch system in be used for the electric feeding unit of pending material.
Background technology
(plating) used in electrolysis at conducting stratum, and pending material is presented the negative pole that is connected to DC source with securing gear via electricity.Opposite electrode is anode in this case, correspondingly is connected to conductivity the positive pole of DC source.Anode and pending material all are arranged in ionogen (electrolyte), and described ionogen comprises the positive charged ions of material to be applied.Because formed electric field between anode and the pending material, they are moved to this pending material and deposit there.
Polarity is respective opposite in electrolytically etching, so pending material is connected to the positive pole of current source.
At least at the end in abutting connection with pending material, electricity is presented and is typically designed to the contact device that adopts terminal folder, pincers or anchor clamps form, so that they can grasp pending material.It is inner at least that whole electricity is presented, and comprises this contact device, then must be made of and yardstick can be designed so that the strong current that runs in practice can be only be transferred to pending material with less power loss and heating electric conduction material.The exact scale design that electricity is presented depends on employed electric conduction material, for example, needs bigger conduction cross section under the situation of relatively poor conductive material.
Electricity present then should be on the surface electrical isolation as much as possible so that, prevent that a large amount of metals also are deposited on electricity and present during the electroplating technology, just when metal deposition is on pending material.Under these circumstances, need in metallization removal technology subsequently, present the removal metal from electricity, to avoid because these accumulation of metal and to the contact device presented from electricity may disturb to the current delivery of pending material.In fact, compare with the surface of pending material, the metal deposition of approximate two to ten times of amounts is on exposed (blank) part that electricity is presented.This is because the virtual resistance device circuit from DC source to pending material, and electricity is presented and is set near this DC source and therefore is positioned at corresponding high potential, makes to take place there that field wire is concentrated and and then cause bigger metal deposition.
With respect to pending material, so exposed electricity is presented the effect of also playing so-called shunting negative electrode (robbercathode).Particularly, near the next-door neighbour that electricity is presented, the metal deposit of not expecting that electricity is presented causes the metal layer thickness on the pending material to reduce.For example when the application to printed circuit card, layer is important to this very uniformly, and above-mentioned situation causes obsolete underproof plate in etching step subsequently.
For fear of this problem, knownly be that the surface that all electricity that can contact with ionogen of electrical isolation are presented is except those section, for example contact areas of the contact device that is used for electrically contacting with pending material.This is because there be not metal can be deposited on the surface of electrical isolation during the electro-plating method.
This insulation is provided by special plastics usually, and described special plastics have high chemical stability, high thermal stability and high-wearing feature.This special plastic insulation layer is by immersing or spraying the and subsequently curing of this layer being applied.If contact device, for example contact area also is insulated during such immersion or spraying coating process, then its need after curing after by for example grinding or polishing mechanically dismantles.If, then be necessary to repeat described immersion or spray technology and curing subsequently in each case because insulation strength harsher required and will apply thicker layer.
Present in order to make this insulator layer that applies adhere to electricity well, electricity present must be before applying thoroughly cleaning and often experience by for example grinding or the extra process of sandblast, so that support adhesivity.
Although fine processing is also used such as Halar
TMThe special plastics of high quality, such insulator layer is still repeatedly damaged by the pending material of sharp edge, particularly when automatic coating unit is used for electroplating device.Insulation is penetrated at these spot failures, and metal will deposit.After the short period of time of only being everlasting, this metal just no longer can remove by cheap electrolysis metallization removal because utilize this method, before all sedimentary metals can be dissolved, to usually relatively the conduction of the spot failure of small area connect and frequently disconnected.In the case, needing to remove the electricity that also chemical metallization removal is relevant presents.If this must finish with too short interval, then this electricity is presented and is presented changing new electricity into.Present if expensive metal is used for electricity, then need fine processing, unless wherein by fusing, burn off or the mechanical treatment conducting plastic isolator of making a return journey, process metal surfaces again, and utilize the plastic insulation layer to apply electricity again and present.All these algorithms all are meticulous and very expensive.
The example that such electricity is presented is represented in Fig. 8.In this case, power on present 2 and following electricity present 3 and end at contact member 12 respectively.For example, following electricity is presented 3 and is fastened in electrolyte bath round-robin chain or the band of tooth is arranged, and owing to corresponding driving move within the figure plane or outside.Power on and present 2 and be mounted to and make it on vertical direction as shown by arrows, to move, and by compression spring to pressing down.Electricity is presented 2 and 3 and is formed anchor clamps thus, powers on to present 2 formation anchor clamps tops and descend electricity to present 3 to constitute the anchor clamps lower sections.Therefore pending material 1 can be clamped between two contacts 12.
Utilization powers on and presents thrust shoe (not shown) on 2, and by means of this electricity present on the tilting plane presented, the anchor clamps of Xing Chenging are can be when entering electroplating region closed and reopen when leaving this district in this way.When it was closed, anchor clamps engaged and are established to the electrical connection of the corresponding utmost point of electricity supply thus with pending material 1.When leaving electroplating region, electricity is presented and is reopened and pending material 1 is further carried by means of the roller path.
Present 2,3 effects of being electroplated and play the shunting negative electrode for the upper and lower electricity that prevents metal, provide above-mentioned thin plastic insulation layer to them as described above, at least to the liquid level of plating bath more than 21.This insulation layer extends the side up to contact 12.
From DE 19735352 C1, know an interchangeable solution.In this case, use the electricity of making by exposed conductive material to present and need not the plastic insulation layer.Present the over-drastic metal deposition for fear of electricity, mask is provided, described mask is provided with widely along the whole electroplating unit that electricity consumption is presented.In this case, mask is rigidly secured to the housing of electroplating unit or is fastened to anode.Mask is made by electrically insulating material at least in its surface, and they are configured such that and only are included in the less migration that ion, particularly metal ion in the ionogen are presented to electricity when electroplating, because these ions can not see through the electrical isolation mask and not have electric current can flow through the latter.On the contrary, described ion is got the path of minimum impedance, is the expected path to pending material in this case.Under this environment, also relate to by the shielding of mask to the field wire in the ionogen.
Gap in the mask must be arranged to make the pending material of the designed maximum ga(u)ge of equipment not touch mask in the case by these gaps.
If in system, handling thin pending material, promptly have the pending material of the thickness littler than maximum ga(u)ge, then this causes the big spacing between pending material and the mask.So so a large amount of ions can migrate to contact member,, whenever can be deposited near the electricity in gap all over thick relatively metal level and present with about 0.1mm or above thickness although make that mask is arranged.As mentioned above, available is in the time before next time, and these metal levels then no longer can remove by electrolysis metallization removal subsequently.
Be used for the thickness that reaches about 0.04mm copper-plated horizontal electroplating system printed circuit board (PCB), easily remove during operation on the contact member or in this undesirable metal level be very possible.Depend on system configuration, exceed the layer thickness of about 0.05mm to 0.1mm of undesirable metal level, then described layer no longer can be easily from the removal of having a few of contact member.The accumulation and removing subtly must be at work stoppage time the in process subsequently time of described layer.Under the every situation all over the layer thickness that exceeds 0.1mm to this layer, expection will have the interference of pair product.
Another shortcoming of this embodiment is that under the situation that the electricity set as Fig. 8 presented, mask can not move with the engagement movement that electricity is presented.
WO99/29931 discloses a kind of equipment that grasps of clamp-like, is used for grasping releasedly electroplating and galvanized object by means of dipping, as printed circuit board (PCB).This grasps equipment and comprises the first leg, the second leg and be used for that following petiolarea at first and second rods contacts with printed circuit board (PCB) and the contact plug that faces toward mutually of clamping printed circuit board.For example with the corrugated tube form contact plug axially on the sleeve of elastically deformable be fastened to each contact plug, and under relaxed state, extend to beyond the contact area of contact plug.When anchor clamps were grasping printed circuit board (PCB), the telescopic free end was placed on tightly on the surface of printed circuit board (PCB) and therefore and has prevented that contact area from contacting with plating bath, thereby prevents the metal deposit on the contact area.
DE 4211253 A1 disclose a kind of electroplating unit, and wherein the workpiece of electroplated is carried in the horizontal channel and passed through ionogen.Made by rotatable trolley wheel in this case with the workpiece negative electrode contact of passing through of advancing, wherein the lid with insulating material is applied to the distolateral of trolley wheel in case the metal deposit of not expecting on the not-go-end side.
DE 100 43 815 C2 also disclose a kind of electroplating unit.In this case, contact with pending material by the bar shaped contact member.For example, use the electrically insulating material of partial vulcanization to prevent the metallization of not expecting to the contact bar that has contact member.
DE 100 65 643 C2 also use and are used for the contact bar that contacts with pending material, and this contact bar comprises the contact insulation, and it covers the contact bar except that the actual contact zone fully.
WO 03/071009 A1 discloses another kind of electroplating unit, wherein electrically contacts bar and is configured in the electrical isolation axostylus axostyle, the metallization that the axostylus axostyle that wherein insulate protection contact bar avoids not expecting.

From contact member 12, with from the small distance of anchor clamps lower section 3 and the shell part 8 of surrounding anchor clamps lower section 3 is fastened to anchor clamps lower section 3.Shell part 8 is designed so that it extends to electrolytical liquid level in the electrochemical processing apparatus more than 21 at least in this case.Shell part 8 can be for example by means of plastic screw or utilize clip 10 to be fastened to anchor clamps lower section 3, clip 10 is formed on the shell part 8 and is latched in after the preglabellar field of anchor clamps lower section 3.Shell part 8 prevents that metal ion is from getting back to the outside of anchor clamps lower section 3 around the electrolyte of anchor clamps lower section 3, and as illustrated in the introduction to this description, this causes the shielding of formed electric field line between antianode (not shown) and pending material or electric the presenting simultaneously.In this example, shell part 8 is opened in the side in the face of anchor clamps top.Yet the closed design that centers on anchor clamps lower section 3 in principle fully also it is contemplated that.
In a similar manner, shell part 7 is fastened to anchor clamps top 2, and at least in the outside, promptly in the face of a side of anchor clamps lower section 3, shell part 7 is squeezed on the anchor clamps top 2 tightly, so that make electrolytical any between shell part 7 and the anchor clamps top 2 may accumulate minimum.In this example, shell part 7 is fastened to anchor clamps top by means of plastic screw 9.Push enough tightly as shell, then fastening by individual plastic screw 9 is enough.
Be similar to shell part 8, shell part 7 is being opened in the face of in the district of anchor clamps lower section 3.
When by the formed anchor clamps open and close in anchor clamps top 2 and anchor clamps lower section 3, firmly relative to each other slide at the formed sliding surface 22 of the point of contact of shell part 7 and 8, make and guarantee good electrical isolation in this case equally, prevent hydraulic seal that metal ion transport is returned and the good shielding of electric field line.The horizontal section that meets in lower section 7 and 8 forms closure surfaces 23.As long as be necessary, grasp pending material 1 and with district that it contacts in, these closure surfaces 23 forwardly cave in, so as to allow to the good fastening of described pending material 1 with contact.When anchor clamps are in closure state, the close pending material 1 of the sunk surface of shell part 7,8, but do not touch it, make to obtain good relatively sealing in this case equally.If desired, remaining little spacing also can seal by soft plastics and seal, and is as described below.Same case is applicable to other surfaces in the face of pending material of shell part 7 and 8, so that be enclosed in the intermediate space that the there is found.
Fig. 1 illustrates the electric feeding unit of Fig. 1 with the view that horizontally rotated 90 ° left, also is in closure state and is being grasped pending material 1, for example printed circuit board (PCB) by anchor clamps top 2 and anchor clamps lower section 3 formed anchor clamps.So pending material 1 is by means of compression spring 6, engage with good electrical connection by means of the contact member between anchor clamps top 2 and the anchor clamps lower section 3 12.In Fig. 2, can be clear that, at least one in shell part 7,8, have depression at front end as mentioned above, make that pending material 1 can be grasped securely.Because shell part 7,8 is fastened to clamp section 2,3, so shell part 7,8 moves with clamp section when open and close.Always sunk surface is therefore identical from the small distance of pending material, is about 0.05-0.3mm, and no matter the thickness of pending material 1.
As mentioned above, sliding surface 22 and confining surface 23 as close as possible being in the same place are to guarantee good sealing.The mode that can further improve sealing will be in following explanation.
In this case, Fig. 3 illustrates the possible configuration of shell part 7, and possible configuration and Fig. 5 that Fig. 4 illustrates shell part 8 illustrate the shell part 7 of configuration in this way and 8 interaction.Fig. 3 a, 4a and 5a with wherein represented, promptly the direction of observation in the plan of Fig. 2 illustrates the details A among Fig. 2.Fig. 3 b, 4b with 5b corresponding side-view are shown and Fig. 3 c, 4c illustrate the edge sectional view of the corresponding line B-B ' of relevant figure a, i.e. vertical view respectively with 5c.As represented in the drawings, for example, shell part 7 has mortise 18 and shell part 8 has tenon 19.These configurations can certainly be put upside down.Shown in Fig. 5 c, the tenon 19 of shell part 8 is bonded in the mortise 18 of shell part 7.This engaging one another as one man obtains near sliding surface 22.If this configuration is used for confining surface 23, then tenon 19 and mortise 18 are inserted into each other and shift out when anchor clamps are opened when anchor clamps are closed again.Realized better sealing between shell part 7 and 8 by such configuration.Therefore in fact there is not ionogen can arrive anchor clamps top 2 or anchor clamps lower section 3.
Near the next-door neighbour of contact member 12, such configuration is impossible, because pending material 1 is bonded on the there.Here, for example, sealing can be implemented shown in Fig. 5 d.In this case, shell part 7 and shell part 8 boths have mortise 18, wherein engage, cooperate or combine with adhesion plastic sealing strip 20.When anchor clamps were closed, plastic sealing strip 20 was pressed to pending material 1 and is therefore sealed surface in contact in this district, but the safety of not damaging basically with pending material 1 electrically contacts.Soft plastics, soft rubber or foam materials are suitable for this sealing.Should note guaranteeing stability about the chemical substance that exists in the ionogen.
As replaceable scheme, can in the zone of action of shell part 7 and 8, provide the sealing of the flat or circle of guaranteeing optimum sealing or shielding.
Usually, do not carry out the process of closed anchor clamps, be immersed in the ionogen up to anchor clamps.Ionogen has been filled in the inside of shell therefore.Because to the good relatively shielding and the sealing of field wire, and the migration that therefore reduces of metal ion, this only causes the less metal deposition of electrochemistry removal easily.
In principle, for example can only be provided at by shell part 7 and 8 formed shells that expection partly has in the district of damage shell when the pending material 1 of loading or unloading.In not damaging generable other district, can provide conventional plastic coatings.
